Disc spring washer is manufactured according to DIN6796 and connected by mid or high-strength bolts and screws. The connection of bolts and screws make compensation for the prevention against the looseness of pull, the abrasion and creeping of wearing parts, thermal expansion and shrinkage as well as sealing element compaction.

The wave springs manufactured by our company are composed of single-layer wave springs (open-ended spring and closed-ended spring) and multi-layer wave springs. Single-layer wave spring shall met JB/T7590-2005 and HG/T2479-2003 standards, as per which we can also design and manufacture various non-standard wave springs on behalf of customers. Given there is no uniform standard for multi-layer wave springs in domestic market, we can produce or design and manufacture various multi-layer wave springs on behalf of customers to meet their

For the connection of flanges with over 100℃ temperature difference and the flange connection of vibrating apparatus, the high temperature disc spring of Shanghai Hegong is the technical assurance to achieve reliable sealing.

Toothed check washer includes S series and VS series, which can be used to prevent against the looseness of bolts incurred due to vibration by increasing the frictional resistance after the connection of washer and bolt.

Composed of the outer ring of inner conical surface and the inner ring of outer conical surface, ring spring plays a buffering function through the shrinkage of inner ring and the expansion of outer ring under exogenic action. It is mainly applied to the circumstances where the space is limited and strong buffering shall be needed.

Truncated-cone scroll helical spring is also called as volute spring or tower spring, featuring small bulk and heavy load.

This company manufactures various different helical/wire springs, including helical spring (compression spring, tension spring, torsion spring), bar spring, leaf spring and wind spring and other elastic products.
